Help distinguishing what music symbol this is? Possibly a multi-measure rest?
I'm a self-taught musician (Soprano/Alto/Teno recorder & piano). I have this score that I was entering into MuseScore so I could access it on my iPad. I've never seen this symbol before. I first thought it might be a multi-measure rest. I entered a multi-measure rest in MuseScore but it only gives one bar. In the image the first staff has two, the second staff has 4 and the third staff has 2. I'm not sure if they are multi-measure rests and if they are how to enter those into MuseScore.
Any guidance and help would be appreciated.
Thanks in advance!
